Fly ash is a waste by-product generated by coal-fired electricity power stations. Due to its environmental impact, there is a growing need for safe and sustainable methods of fly ash disposal. One effective approach is the beneficiation of fly ash through the production of zeolites—a class of

The North-West University (NWU) has pioneered the novel use of Europium-Tellurium-Oxide (ETO) in the production of clean energy. ETO is a light-chargeable catalyst material that exhibits sustained and enhanced activity after light excitation has ended. Its unique characteristics present an

This technology involves a method for generating hydrogen in an electrolysis cell. A proton exchange membrane (PEM) is used to separate anode and cathode chambers of the cell. The space between the anode and the PEM is filled with aqueous sulfuric acid. In use, gaseous sulphur dioxide is fed to the

This technology utilises a microchannel reactor for the decomposition of ammonia, comprising two chambers: one for exothermic combustion of ammonia to generate heat. A second chamber of the reactor with a second catalyst receives a second stream of ammonia to provide endothermic decomposition of the

The North-West University (NWU) has developed and patented a method for producing hydrogen via hydrolysis, using an activated aluminium compound. Technology Benefits: Aluminum also can be recycled after the hydrogen production process. Hydrogen can be produced under high pressure. By-products are

Many of the commonly used food preservatives and microbial agents are synthetic compounds. In recent years, there has been an increased interest in avoiding or eliminating the use of synthetic compounds and in developing and promoting the use of natural materials for use as antimicrobial agents

A novel bioreactor system that uses membranes to create a compartmentalised system where two or more species can be co-cultured without mixing of species, while ensuring rapid exchange of metabolites and proteins between compartments and shared medium composition. The system operates continuously

The CSIR has established a bioconversion platform that focuses on alternative pathways for chemical production. The platform is geared towards local production and replacing imports of bio-based platform chemicals, including lactic acid. This shift will have a direct impact on the bioeconomy. The

Hydrogen and fuel cell technologies offer zero emissions and are a clean alternative to fossil fuels. HySA Systems, at the University of the Western Cape, have made improvements in the performance, reliability and cost competitiveness of fuel cell components and systems. These have been demonstrated

This invention relates to a Femtosecond Laser-based method for the fabrication of micro- and nano-constriction type structures on a YBa2Cu3O7-x Superconducting thin film and to a new superconductor device. According to one aspect of the invention, there is a method of manufacturing micro- and nano

A system which harvests thermal energy from various sources such as sunlight, cars, power plants, factories and other industries, and converts it into electricity. The harvested heat energy is stored in a storage tank, with water used as an energy storage medium. This then flows along a gradient to

A low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate velocity wind and generate electricity efficiently for household use. Large-scale wind turbines in South Africa are located far afield, and the energy generated must be transported back to communities via huge
